We retrospectively studied all gastrostomy buttons inserted in the Royal Children's
Hospital, Brisbane between 1988 and 1995. One hundred and thirty-two patients (M = 60, F=72)
and 388 buttons were analysed. Intellectual handicap and cystic fibrosis comprised the majority of
patients. Thirty-three patients had gastrostomy buttons inserted primarily, whereas, 99 patients
received gastrostomy buttons inserted into matured gastrostomy stoma. The average longevity
of all determined buttons (n = 280) was 360.43 days (SD = 310.24 ). The first buttons inserted
primarily (n = 25) had longer longevity than the first buttons inserted into matured gastrostomy
stoma (n = 82) with statistical significance. The average longevity of subsequent buttons was
significantly less than the first buttons. Valve incompetence and leakage of gastric content around
the shaft were the most common causes of button removal. We concluded that the gastrostomy
button is the method of choice for long term enteral feeding in children.
